md-is-error not working on md-input-container with md-select

Question

I use md-is-error to show error. It works fine in input but not working in md-select. This is my code:

<div ng-controller="AppCtrl" layout="column" ng-cloak="" class="inputdemoErrors" ng-app="MyApp">

  <md-content layout-padding="">
    <form ng-submit="projectForm()" name="testForm">

      <div layout="row">
       <md-input-container class="md-block" flex-gt-sm md-is-error="project.postalCode == undefined && testForm.$submited">
            <label>Postal Code</label>
            <input ng-model="project.postalCode"
                   required name="ptCodeInput">
          </md-input-container>
        <md-input-container flex="50" md-is-error="project.type == undefined && testForm.$submited">
          <label>Project Type</label>
          <md-select ng-model="project.type" required>
            <md-option value="app">Application</md-option>
            <md-option value="web">Website</md-option>
          </md-select>
        </md-input-container>
      </div>
      <div>
        <md-button type="submit">Submit</md-button>
      </div>
    </form>
  </md-content>
</div>

My code works fine with Postal Code, but Project Type selection it not working.

Have any suggestion for use md-is-error in md-select?

Answer 1

There is already an issue raised for the same

md-select is missing md-input-invalid

It shows the error message when there is a change such as ng-blur.

Hope it helps.
